We tend to argue back against lies: it is absurd to think that Democrats cheated in Republican-run Arizona and Georgia. Arguing back on social media often just drives attention to an issue, making it clear what the sides are.
Fact-artillery: well aimed facts that hit the other side in their lies, corruption or hypocrisy, but done as if speaker and listener are other sides in an artillery battle. And what we (all) do when outsiders start blasting us is dig deeper foxholes. What kind of conversation might pull honest people out of their fox holes? What kind of conversation doesn't have you and your listener on opposite sides — maybe you are in opposition to a politician, but on the same team with voters who don't yet agree with you?
